我的角度应用程序有一个名为'listdata.component.ts'的组件。在此组件的ngOnInit()中,发生了2个api调用。但是,当针对2个请求获得401响应时,注销api调用将发生2次。我的拦截器代码
@Injectable()
export class TokenInterceptor implements HttpInterceptor {
notificationItem: any;
constructor(public authService: AuthGuardService, private router: Router, private notification: NotificationService) { }
intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
if (this.authService.tokenValid()) {
const authReq = request.clone({ headers: request.headers.set("Authorization", 'Bearer ' + this.authService.getToken()) });
return next.handle(authReq).do((event: HttpEvent<any>) => {
}, err => {
if (err instanceof HttpErrorResponse) {
if (err.status === 401) {
if(authReq.url.indexOf('/logout') > -1){
localStorage.clear();
this.router.navigate(['login']);
}
else
{
this.authService.logout()
}
}
}
});
}
else{
return next.handle(request);
}
}
}
我想在一次401响应后取消所有401请求,并且只注册一次注销。如果takeUntil()运算符可以解决我的问题吗?。提前谢谢。
